About EDAP TMS SA

EDAP TMS SA today markets Ablatherm
®
for high-intensity focused ultrasound
(HIFU) for prostate tissue ablation in the U.S. and for treatment of localized prostate cancer in the rest of the world. HIFU
treatment is shown to be a minimally invasive and effective option for prostatic tissue ablation with a low occurrence of side
effects. Ablatherm-HIFU is generally recommended for patients with localized prostate cancer (stages T1-T2) who are not candidates
for surgery or who prefer an alternative option, or for patients who failed radiotherapy treatment. Ablatherm-HIFU is approved
for commercial distribution in Europe and some other countries including Mexico, Chile, Brazil and Canada, and has received 510(k)
clearance by the U.S. FDA. The Company also markets an innovative robot-assisted HIFU device, the Focal One
®
, dedicated
to focal therapy of prostate cancer. Focal One
®
is CE marked but is not FDA approved. The Company also develops
its HIFU technology for the potential treatment of certain other types of tumors. EDAP TMS SA also produces and distributes medical
equipment (the Sonolith
®
lithotripters’ range) for the treatment of urinary tract stones using extra-corporeal
shockwave lithotripsy (ESWL) in most countries including Canada and the U.S. For more information on the Company, please visit
